-. SHINGLE;

Application filed February 7, 1927; Serial No. 156,505.

This invention relates to shingles and more particularly to improvements therein tending to simplify, render more efficient and improve generally articles of this character.

One of the objects of this invention is to provide a shingle construction formed with a tongue out from the material ofthe shingle sist the action of wind upon the exposed edge which tends to force or raise the same upwardly.

Another object of my invention and an advantage obtained by reason of the aforementioned construction is that'of preventing relative lateral displacement of the shingles. This advantage is obtained by vhaving the longitudinal dimension of the notch orrecess substantially the same as the longitudinal dimension of the tongue so that upon en gagement of the tongue of one shingle with the recess of another relative lateral displacement between the shingles is prevented.- The inter-engaging'tongues and recesses of the shingles also provide for automatically spac ing the shingles both laterally and vertically.

Another object of this invention is to ro- I vide a shingle having means to facilitat the starting of the shingling adjacent, for instance, the edge of the roof and to this end my invention contemplates the provision of notches or recesses along both longitudinal edges of the shingle whereupon a series of shingles may be secured in reversed position upon the roof with the notched straight edges thereof parallel with the edge of the roof to thus provide means wherehv-the shingling operation can be started with ease and fa cility. This eliminates thenecessity of an objectionable practice now quite universally followed of'having on hand a supn of s e-c cialshingles adapted for starting the shingling operation at the edge of the roof.

The various objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in c0nlying wherein Figure l'is a plan view of a plurality of shingles, constructed in accordance with my.

invention and illustrating the manner in which they are applied to a roof or the like.

.Figure2 1s a plan view of one of the shin- )gles;

Figure 3 is an enlarged detail sectional nection with the accompanying drawings view taken substantially on the planeindicated by line3--3 in Figure 1, and

Figure 4 is a perspective view illustrating more in detail the interlocking connection between adjacent shingles.

R ferring .now more particularly to the drawings wherein like reference characters indicate like parts, it will be notedthat I may form my shingle in units or strips 10 each of which comprises a pair of point-down shingle ends 11 thus producing a double or twin shingle unit. However, as will be obvious as this description proceeds, the same advantageous results may be'obtained if sin gle shingle units are produced such as indicated by dotted line 12 or if desired units of greater length comprising three or more shingle ends may be produced.

Each unit, and preferably each shingle end 11, is formed with a tongue 13 cut 'from the material of the shingle and normally in the same plane as the body of the shingle until the same is deflected out of this plane for engagement with notches or re-' cesses of adjacent shingles, yet to be referred to. In this connection each shingle unit is provided with one or more recesses 14 in the longitudinal edge adjacent to which the tongues 13 are formed and one or more recesses 15 in the opposite longitudinaledge. These recesses 14 and 15 are formed either by cutting away the longitudinal edge intermediate the ends or by notching the edges at the.

ends thereof as indicated at 16'. Thus the notches 16 of abutting ends of adj acently arranged shingles together form recesses 14 or ice 15 as suggested by full and dotted lines in Figure 2. L v

In applying the shingles 'to a roof or, wall, or the like the tongue 13 of one shingle is caused to engage the recess 14 in the edge of the underlying shingle as most clearly illustrated in Figure 3. This not only provides means for holding down the exposed edge of the last applied shingle but also prevents relative lateral displacement between the intar-engaging shingles and provides means for automatically spacing and aligning successively applied shingles with those previ ousl placed.

T e recess 15 arranged in the straight 1ongitudinal edge of the shingle may, by reversing the shingle so that the shingle ends 11 polnt upwardly insteadof downwardly, be brought parallel with, for instance, the edge ofa roof and when the shingle is secured in this position t the roof the recess 15 may be engaged by the tongues 13 of the first row of shingles so that the shingling operation may be started with facility and the successively .applied shingles properly aligned and spaced.

are applied to a roof or the like the tongue 13 may be conveniently caused to engage the recess 14 by means of a tool inserted through the opening formed by'the tongue which tool extends into the recess 14 to guide the tongue I into the recess and under the edge of the shingle. After the tool has been removed the shingles are secured to the roof or other surface by nailing the same in the customary manner. When thus secured the tongue or tongues of one shingle" are engaged in the recess or recesses 14 of an under ing shingle and extend under the edge of tii ing shingle.

While several possible modifications of the herein described and illustrated structure is underlyhave been suggested, various other changes ma be made in any of the essential and all 0 the nonessential details without departing from the spirit and scope of this invention and to this end it will be'obyious that v reservat1on is made to make such changes as may come within the purview of the accompanying claims.

What I claim as my invention is 1. A shingle unit formed with a tongue-adjacent one longitudinal edge thereof and recesses in the longitudinal edges, said tongue constituting a lockin tab adapted to engage the recess in either; ot said longitudinal edges of an underlying shingle.

2. A shingle unit formed with a tongue adjacent one longitudinal edge thereof and recesses in" the longitudinal edges, the recess in one edge being in ali nment with the recess in the other edge where y said tongue may engage one recess of an underlying shingle when the latter is used as a'startin shingle, and the other recess when the sai shingle is used as an intermediate shingle.

3. A shingle unit comprising a body or tion having spaced wings projecting rom one longitudinal edge thereof, and tongues formed on said wings, said shingle having a recess in its edge between said wings and V a second recess in its opposite longitudinal edge in alignment with the first mentioned .rec'ess whereby a tongue may engage one recess of an underlying. shingle when the latter is used as a starting shingle and the other recess when saidshingle is usedas an intermediate shingle. e

In testimony whereof I aflix si nature. "JOSEPH P.
